SPECIFICATION forming part of Letters Patent No. 647,567, dated April17, 190). Application filed January 27, 1899. Serial No. 703,622. (Nomodel.)

Be it known that I, ORANGE JULL, of the city of Toronto, in the countyof York and Province of Ontario, Canada, have invented certain new anduseful Improvements in Feathering Paddle-Vheels5 and I hereby declarethat the following is a full, clear, and exact description of the saine.

This invention relates to certain new and useful improvements inpaddle-wheels, and to so construct the paddle-wheel that the buckets orpaddles will enter the Water without percussion or jarring and whensubmerged present their full area to the water to take advantage of itsentire resistance and to leave the water without lifting it or raisingaswell is the object of the present invention; and it consists of apaddle-wheel embracing in its construction two side frames, consistingof the usual centers, arms, and rings revoluble with the paddle-wheel,and a series of independent paddles or buckets carried by the sideframes arranged to be set at any predetermined angle to the verticalaxis of the paddle-wheel and revolved about their own axes during therevolution of the paddlewheel in order that they will continuouslyduring the revolution of the paddle-wheel maintain their same relativeposition to its vertical anis, as hereinafter more fully set forth, andmore particularly pointed out in the claim.

In the drawings, Figure l is a perspective view of a paddle-wheel,showing the paddles or buckets moved into a position in which theirfaces are substantially at right angles to the vertical axis of thewheel. Fig. 2 is a y view of a modification showing the paddles orbuckets moved into a position in which their side faces aresubstantially parallel with the vertical anis of the wheel. Fig. 3 is atransverse sectional view through the paddlewheel and shaft.

Like letters of reference refer to like parts throughout the specieationand drawings.

A A represent the two side rings or wheels 5 B B, the arms; C (l, thecenters, and D the hub of the paddle-wheel. This much of thepaddle-wheel is similar to the paddle-wheels ordinarily used.

E E represent the paddles or buckets, each of which consists of a hub c,substantially equal in length to the distance between the rings A A,with sufficient clearance to allow of the free rotation of the hub, andtwo blades e' e projecting from opposite sides of the hub c. Each of thehubs e is secured by a pin S on a shaft F, the ends of which arejournaled in the rings A A. The length of the shafts F F is slightlygreater than the entire width of each of the paddles or buckets E E, inorder that sulhcient space will be provided for the free revolution ofthe paddles or buckets. The same end of each of the shafts F is providedwith a crank G, by means of which the shafts and paddles or buckets arerotated. Each of the cranks G is provided with a crank-pin I-I.

I represents a frame coupling together the crank-pins and by means ofwhich the cranks and paddles or buckets are caused to move in unison.The relative position of all of the cranks to their respective paddlesor buckets is the same in order that the paddles or buckets can all bemaintained in the same relative position to the vertical axis of theshaft of the paddle-wheel- As shown in Fig. l of the drawings, the frameI is provided with an an nular center J.

K represents the shaft of the paddle-wheel, to which the hub D isrigidly fixed. The shaft K is journaled in bearings L. Passing throughone of the bearings L and surrounding the shaft K is a sleeve M, to theinner end of which is fixed an eccentric O and to the outer end of whichis connected a crank P. The eccentric O is substantially of the samediameter as the center J and has its periphery formed with an L.-shapedIiange, producing an offset bearing-surface for the center J, which thenacts as an eccentric-strap for the frame I. .By means of the crank P theeccentric O can be moved into any predetermined relative position to thevertical axis of the shaft K and carry with it the framcI to alter therelative angle of the paddles or buckets to the vertical axis of theshaft. The paddlewheel revolves with the shaft K and during itsrevolution carries with it the frame I. The revolution of the frame Iabout the eccentric O turns the paddles or buckets E E about theirrespective shafts and continuously maintains them at the same relativeangle to the vertical axis of the shaft K. In other words,

IOO

if the paddles or buckets E E are set perpendicular the revolution ofthe paddle-wheel will cause the frame I to continuously turn the paddlesor buckets E E about their shafts and maintain them continuously in aperpendicular position during the revolution of the paddle-wheel, sothat the paddles or buckets can enter the water in a perpendicularposition and pass through and leave the water in the same position inorder that the entire resistance of the water may be taken. advantage ofto propel the boat and also to prevent the paddle-wheel lifting thewater or raising a swell during its revolution.

Instead of using the eccentric and annular center, as shown in Fig. l ofthe drawings, it is possible to provide the sleeve M with a crank Q andconnect it to the frame I by means of a pin for the purpose of shiftingthe position of the frame to vary the inclination of the paddles to thevertical axis of the shaft.

Having thus fully described myinvention, what I claim as new, and desireto secure by Letters Patent, is

A paddle-wheel embracing in its construe- ..V

tion two circular side wheels having radial spokes connecting with acentral hub, a shaft on which the hub is keyed, a journal-bearing inwhich one end of the shaft is mounted, a sleeve loosely mounted on theother end of the shaft, a journal-bearing in which the sleeve ismounted, a crank-handle on the outer end of the sleeve, an eccentricring on the inner end of the sleeve, an inwardly-prei jecting L-shapediiange on the periphery of the eccentric ring forming an offsetbearingsurface thereon, a series of revoluble paddles journaled in theside wheels, a crank connected to each paddle on the outside of one ofthe side wheels, a frame in which the free ends of the cranks arejournaled, and a central ring connected to the frame and journaled onthe L-shaped Harige, substantially as described.
